Yeah poor is more like it as if there were no connectivity at all then
there won't be a need to use internet resource better.

You are very right about this and this perhaps is one of the reasons why
some ISPs don't won't to support hosting such servers especially in my
region where bandwidth cost is still on the high side. (Which is one of the
processes I refer)

have cheap bandwidth you wish to donate to the global
And the answer to that question by many ISP in this region will be a NO so
the cost remains at end user table ;). This is one of reason why hosting
like this are easier done within IX who normally don't always look at the
business but considers local benefits as priority.

beginning but not the end of the discussion. The technical question is
whether a locale is being served well enough. "Well enough" is usually
measured in terms of delay to get an answer to a look up, e.g. 89
milliseconds, and reliability, e.g. answers are received 99.923% of the
time. (Both of the numbers in the previous sentence are illustrative and
not related to any actual measurement. I made them up as I typed.) On the
other hand, many people seem concerned with political questions, e.g. which
countries are important enough to have root servers. It would help the
discussion to know what questions are being asked. The list of root server
locations may or may not be relevant.
